I definitely suggest configuring snapraid so it points to the drivepool folder with the GUID inside the config file so that it's much easier to restore. Snapraid doesn't have to be the root of the drive, it can be anywhere you like (as long as they are on different psychical drives).
So instead of doing:
data d1 z:\
data d2 y:\
data d3 x:\
You do:
data d1 z:\drivepool.{guid}\
data d2 y:\drivepool.{guid}\
data d3 x:\drivepool.{guid}\
That way after a failure e.g d2 dies, you drop your new drive in, add it to the pool, get the new GUID from the new drive, and edit your snapraid conf to comment out the old drive and add the new one by changing d2 y:\drivepool.{guid}\ to d2 y:\drivepool.{newguid}\ like so:
data d1 z:\drivepool.{guid}\
#data d2 y:\drivepool.{guid}\
data d2 y:\drivepool.{newguid}\
data d3 x:\drivepool.{guid}\
Then run your fix and it all just works - and you don't have to move your files around.
